To obtain a jaw model which is capable of easily, rapidly and distinctly presenting various methods of fixing prosthetic teeth to the upper jaw or lower jaw by installing an anchor member movable by the effect of a spring between a first fixing position where the end of the anchor member is made flush with a main body surface and a second fixing position where this end projects from the main body surface in such a manner that the anchor member is not disengaged into the hole.

The anchor member 2 is made movable from the first fixing position of a non-projecting state to the second fixing position of a projecting state by an operating button 3. In the first fixing position, the end of the anchor member is flush with the main body of the model and, on the other hand, in the second fixing position, the end of the anchor member is in the state of projecting from the surface of the main body of the model like the end of a dental root or implant. The main body 1 of the model is provided with a hole 10 for housing the respective anchor members and the spring 14 to press this members while including a rod 13 so as to compress the anchor member 2 is disposed between the bottom 11 of the hole 10 and the flange 12 of a base part 7 so as to project the anchor member 1 from the hole 10.
